Justin Koehneke and Seth Friedman entered the Shark Tank to pitch Bottle Bright. They asked for $75,000 for 15 percent of the company, that makes environmentally friendly cleaners for reusable beverage containers.

The cleaning solution comes in the form of an effervescent tablet that you place in the bottle to clean stains and remove odors.
In the end, Lori Greiner invested $75,000 for 33 1/3 percent of the company, which is called Clean Ethics.
